A wealthy person once told me "To attain nice things, you buy the best you can afford and take care of it always".......Good Advise when it comes to things you'll always keep. That statement doesn't apply to anything that plugs in, as these items are, in the long run, disposable.
I owned a janitorial service for 13 years, salesmen always wanted to sell me on the latest Kirby vacuum at $1000.00 a pop, telling me it's the last vacuum I'll ever purchase. Being that I'm the type that wants to take advantage of new technologies as they come along, I always declined.
Cheaper items that get replaced regularly are sometimes a better investment than expensive items that you keep much longer, in order to get a return on your investment.
2 years from now, LED fixtures will be much cheaper still and you may want to go that route, and can because you're not stuck with an expensive MH system that you can't unload, because everyone else wants LEDs as well.
I looked at some $400.00 MH systems for my cube two years ago, but bought a used Coralife clamp on for 100.00. Now I'm looking at $200.00 LED fixtures to replace the clamp-on model. Both lights together will still cost me $100.00 less than the top of the line MH system I was looking at, which would have been two years old by now. Had I bought the top line MH model two years ago, then LED wouldn't be a possibility for me now.
I've been doing saltwater for 25 years now. This is just an equipment lesson I had to learn, being that I personally have a very finite budget in which to spend in this hobby.
Edit: I didn't post that the Odyssea Lamps are impossible to replace, only a b*tch to replace...
I still think the Odyssea fixtures are a valid option for someone just getting in the hobby. Piecing together a lighting system is like reinventing the wheel to a noob, since they probably need to be focused on learning chemistry.
Its a plug n play all in one fixture. I used one for a few years when I got back in the hobby after a break. They do a good job for what they are, without having to sweat the cost.
